93549-74-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93549-74-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,5,4 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 93549-74:
(7*9)+(6*3)+(5*5)+(4*4)+(3*9)+(2*7)+(1*4)=167
167 % 10 = 7
So 93549-74-7 is a valid CAS Registry Number.

Hanack, Michael,Rieth, Robert
, p. 1487 - 1489 (2007/10/02)
Cyclodeca-1,3-dien-5-yn-1-yl trifluoromethanesulphonate (2) has been synthesized and solvolysed in different solvent systems to give cyclized aromatic products exclusively, which are formed mainly via an aryl cation (5) intermediate.
